The police are stymied by a lack of witnesses and clues as they investigate the murder of a pretty coed in San Francisco park. Hoping to arouse the conscience of The Public, Ironside (Raymond Burr) appears on an all-night TV debate show, begging people to come forward with any information that might help collar the killer. The Chief hopes that he can either panic the perpetrator into tipping his hand, or play for time until his assistant Ed Brown (Don Galloway) can ferret out the one clue that will crack the case. Featured in the cast is a young Ed Begley Jr. (who undoubtedly was bicycling to the studio even back in those pre-Global Warming days). ~ Hal Erickson, Rovi
